/**
 * \brief 	Bit stream container
 *
 *	Structure for byteArray/file stream.
 *
 *	# General
 *	.size defines the maximum size of the byte array (see .data)
 *
 *	.data points to the input/output array of bytes (unsigned char*).
 *
 *	.pos has to be set to an pointer to an 32 bit long unsigned integer (uint32_t *)
 *	 as this variable is read/write.
 *	 Therefore it is best practice to declare the variable itself and use the &-operator
 *	 to assign the address. The value of that variable points to the position inside the
 *	 buffer where the stream begins. Which is usually the first (0th) byte but can also be
 *	 another value if there more information transferred in that stream.
 *	 After processing .pos points to the next "available" byte (if any left).
 *
 *	.buffer has to be set to 0 for internal use only (single byte buffer)
 *
 *	# Receiving data (input)
 *	.capacity is used for addressing single bits in the actual byte (see .buffer)
 *	 and has to be set to 0, which means there are 0 bits read so far and a new
 *	 byte needs to be read from the input stream/data-array to the current byte buffer.
 *
 *	# Sending data (output)
 *	.capacity is used for addressing single bits in the actual byte (see .buffer)
 *	 and has to be set to 8, which means there are still 8 bits left to fill up
 *	 the current byte buffer before writing the final byte to the output stream/data-array.
